The Edward-Dean Museum & Gardens opened in 1958 and was founded by Edward Eberle and Dean Stout. The museum features late 16th to early 19th century European & Asian Fine Arts. Dean Stout designed the interior spaces of the museum to create a home-like atmosphere with the intent to share with the visitor a first-hand experience of the ambiance of the time period. The museum and its 16-acre campus originally came under the County in 1964.

On July 1, 1999, the Edward-Dean Museum & Gardens was shifted to the Riverside County Economic Development Agency.

The Edward-Dean Museum & Gardens is open Thursday through Saturday from 10am – 5pm. General admission is $5. The museum hosts three special exhibits a year and a variety of events. The facilities are available for rent and are ideal for weddings, receptions, and meetings.
